Specification of Letters Patent.- PatehteulApr. 25,1911;

Application filed July 28, 1910. Serial No. 574,225. I

To alluvho'm it may concern."

.Be-it known. that I, Gnome H. Dawson, a citizenof the United States,residing at Fort -Madison, in the county of Leeand State of Iowa, haveinvented a new and useful Flange-Lubricating Device, of which thefollowing is a specification.

My invention relates to an improvement in the class of' dev1ces used onlocomotives and cars for lubricating the flanges of the 4;.

' wheels to decrease their friction upon the inner sides of therail-heads against which they ride and accordingly diminish the wear onthe flanges and the rails.

In the accompanying drawing, Figure 1 shows my im roved device inelevation operatively app ied to-a wheel-flange; Fig. 2 is a sectiontaken on line AA, Fig. 1, and enlarged, or on line A-A, Fig. 3; and Fig.3 is an enlarged longitudinal section on line A cyl'ndric'al casing 4,formed preferably ofmetal, open atboth ends, with an internal shoulder 5near its forward end, which is shown tapering, is adapted to be fixedlysecured in operative position, as through the medium of parallel Wings 6extending from it. Fitting within the case to reciprocate longitudinallytherein, is a tube 7, shown of massive construction, having a reducedforward-end portion 8 forming a shoulder 9 to normally engage, asa stop,with the shoulder 5, and containing, by preference, near its outerextremity, a packing-ring 10; and the rear end of the sleeve is alsoreduced in diameter, as shown at 11, to.present a' shoulder 12, againstwhich a relatively strong spiral spring 13 is confined, as by a plug 14screwing into the rear 'end of the casing, This plug has a stud, 15extending from it cent-rally into the casing, with a tapering tip 16projecting from it and shown as entering the stud, though it may be anintegral part thereof,v About this stud is confined at its rear end-arelatively light spiral spring '17- terminating at its forward end in aseating-head 18 for a pencil 19 of graphite, or other suitablelubricating material, which is reciprocatingly confined in the tube 7against the spring-head.

While the lubricating medium is described as a pencil, it may be apencil of tubular form, for containing the lubricant, as the 'core, inliquid or other condition.

The device maybe operatively applied to a wheel'20, as that of alocomotive, by sebent to extend horizontally, as represented or" at'asuitable angle to the flange of the wheel, inserted between the wings 6and bolted thereto. With the device in.posi-- tion, the end of thepencil 19 bearsagainstthe outer face of the wheel-flange to lubrie cateit; and as the pencil wears away-the.

expansion of the spring 17 protrudes it to maintain its contact with theflange. More or less slight swerving of the .wheel on'its track iscompensated for by the yield of the spring 17', which will permit suchswerv ing to force the pencil inwardly until its advance-end is flushwith that of the tube 7,

when it will still perform its'lubricating.

function; To prevent excessive s'werving of the wheel, as in rounding acurve, from encountering a rigid part of the device, which would tend tobreak it, the spring-pressed tube 7 is provided to yield underthe'strain' and thus prevent such injury.

The washer 10 serves as a guard against dust andlother foreign matterentering the device and impairing its action.

What I claim as new and desire to secure by Letters Patent is- 1. In aflange-lubricating device, the combination of a spring-pressedreciprocating tube, and a springpressed head confined .to reciprocate inthe tube and having a seat for a lubricating pencil to maintain theadvance end thereof in contact with the flange of a locomotive or carwheel adjacent to whicl said device is supported.

2. In aflange-lubricating device, the combination of a case adapted tobe supported. relative to the flange of a wheel on a-loco motive or car,a spring-pressed tube rec procaloly confined in the case, and aspringpressed lubricating-pencil reciprocably con-- fined in the tube,for the purpose set forth. In a flangelubricating device, thecomhinationof a case adapted to be supported relative to the flange of awheel on a. 1000- motive or car, a tube in the case, a relatively strongspring in the case, against which the tube is confined to render itlongitudinally reciprocating, a head in the tube foaming alubricating-pencil seat. and a-relatively weal:

4;. In a flangelubrieating device. the comhination of a case open at itsends and adapteuring 'a bracket 21, in suitable'position onthe'truck-frame', indicated at 22 in Fig. 1, y and having theend-portion of the bracket,
